Most investigations concentrated on the shape of baffle blocks. In this study, the hydraulic performance of a new shape (as W shape) baffle was tested. Three W baffle models were made of fiber glass, with different angles (45\u25cb, 60\u25cb and 75\u25cb). The range of the discharges in a glass channel are from 76 to 279 cm3\/s\/cm. These discharges were used and controlled in such a way that the Froude number for all the tests upstream the models ranged from 4.5 to about 10.5. Generally, the results showed that all models contribute an increase of E%, but the baffle with an angle of 60o and Lb = 10 cm gave a height value of E% close to 85%. Also, at this angle, Lb gave the minimum relative length of jump. According to the results of this study, it can be considered that the W shape baffle is more efficient than other shapes since it provide a high dissipation of energy and lowering dimensions of the stilling basin. So, due to high dissipation of hydraulic energy and lower length of hydraulic jump in W shape baffles, it is recommended to be used in prototype future design of stilling basins.<\/p>\n<p><strong>Keywords<\/strong>: Hydraulic structures, hydraulic performance, Stilling basins, Baffles, Hydraulic jump.<\/p>\n<p>[button href=&#8221;https:\/\/conferences.tiu.edu.iq\/iec\/wp-content\/uploads\/2018\/02\/IEC2017_A1_Evaluation-the-Hydraulic-Performance-of-W-Shape-Baffles-in-Stilling-Basins.pdf&#8221; size=&#8221;medium&#8221; textcolor=&#8221;#ffffff&#8221;]Full Paper (PDF)[\/button]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>3rd International Engineering Conference on Developments in Civil &amp; Computer Engineering (IEC2017) Title: Evaluation the hydraulic performance of W shape Baffles in stilling basins Authors: Hamid H.
